@jtratner I wanted to point out that the columns must be clearly (visually) separated. You cannot have:
```
12foo
23bar
34baz
```
And expect to get two columns using the sniffing. Also they must be a valid fwf, so this:
```
12 foo
12344 bar
334 baz
```
Even though it's clearly separated is not a valid fwf.
